Edo-period at Japan suffers a big cultural shock.
First, the aliens invaded the earth, overpowered the nation’s government, disbanded carrying swords for the once proud samurais.
moreover; these aliens took the people’s jobs and are currently running a sweatshop using them as laborers.
going with the flow, Sakata Gintoki, an enigmatic vagrant samurai whose personal trademark is not only his naturally permed silver hair but also his love of anything sweet and addiction to Shonen Jump is making a life out of this chaotic era.
He is self employed in a do-it-all shop named Yoruzuya Gin-chan who offers any job for any amount of money.
Their jobs range from searching lost kittens and saving the world.
Sakata Gintoki is a samurai living in an era when samurais are no longer needed.
To add to his troubles, oppressive aliens have moved in to invade. Gintoki lives with Kagura and Shinpachi, taking on odd jobs to make the world a better place…and to pay their rent.
其后更颁布了「废刀令」, 夺走了武士的刀, 使他们无力反抗。自此, 天人横行霸道, 幕府为天人所影响, 甚至被控制, 成为了「傀儡政权」。在这样的时代, 有一个武士与同伴愉快地过着异想天开的生活。
